Explain what you mean by "build". Using the following: . ./oe-init-build-env build-test bitbake core-image-core --- time passes, git pull pulls in changes --- bitbake core-image-core The second "build", only the changed packages will be added to the image. You you are using different build directories, then it doesn't re-use anything. The purpose of this is incremental software development within a single build directory. --Mark > _______________________________________________ > Openembedded-core mailing list > Openembedded-core@lists.openembedded.org > http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
